Must Have Generator Accessories

Transfer Switch

Any backup power system needs a transfer switch as a key component. This device lets you switch between your primary power source and a backup generator during an outage. Without a transfer switch, connecting your generator directly to your home’s electrical system can cause serious injury, damage to your home’s electrical system, and even death.

  • Transfer switches come in two varieties: manual and automatic.

Manual Transfer Switch

A manual transfer switch requires you to physically switch the power source between your primary source and your generator. Turning off the main breaker and connecting the generator’s power cord to the transfer switch will accomplish this. A manual transfer switch is affordable and reliable for small backup power systems.

Automatic Transfer Switch

On the other hand, an automatic transfer switch will switch to your backup generator when it senses that your main power source isn’t working. It can turn on the generator, transfer the load, and shut it off when the primary power source returns. Larger residences or businesses that want a steady power source in the event of a power outage will find this a fantastic solution.

It’s crucial to have a professional electrician install your transfer switch. Incorrect installation can lead to electrocution, fire, and other hazards. They can also ensure that your transfer switch is correctly sized for your generator and home’s electrical load.

During power outages, heavy-duty extension cords connect your generator to your home or appliances. They provide the necessary power transfer while ensuring safety and reliability. When selecting an extension cord for your generator, it is important to consider factors such as amperage, length, and thickness.

An extension cord’s amperage rating tells you how much electricity it can safely handle. If you use more amperage than the cord can handle, it could overheat and start a fire. The length of the cord is also important, as longer cords can cause a voltage drop, which can damage your appliances or cause them to operate inefficiently. The thickness, or gauge, of the cord, is also critical. A higher gauge number indicates a thinner wire, which can result in increased resistance and reduced power transfer.

It’s important to note that heavy-duty extension cords should only be used temporarily, as they are not designed for long-term use. If you need power all the time, you should have a professional install a transfer switch and connect your generator directly to your home’s electrical system.

Lastly, if you need help deciding which extension cord to buy, it’s always best to ask a professional. They can help you choose the right cord for your generator based on how much power it puts out and what it needs. By doing these things, you can make sure your generator works well and safely when the power goes out.
